Abstract

The invention relates to an interlock for a column, comprising a piston with a piston rod, such that the piston rod is disposed in a claw bush, the claw bush being disposed in a single- or multi-part plate, such that the piston and the claw bush can move in the single- or multi-part plate. In one embodiment, the claw bush has at least two stages, to apply the force in a distributed manner, the contour of the stages corresponding to the end of the piston rod and/or to the end of the column, the average radius of the first stage differing from the average radius of the second stage.
